BrownfieldGramercy, St James, Louisiana · Atalco Gramercy LLC
Atlantic Alumina, Gramercy Operations is a natural gas plant in Gramercy, St James, Louisiana, retired 2010-02-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 32 MW of generation, so the grid hookup, transmission rights, and often cooling-water access are already in place — collapsing the speed-to-power timeline versus a greenfield build.
